US-Total Electron Content Product (USTEC)
The US Total Electron Content (US-TEC) product is designed to specify TEC over the Continental US (CONUS) in near real-time. The product uses a Kalman Filter data assimilation... -
Calculations of the Total Number of Electrons Along a Ray Path Extending from the Transmitter to the Receiver
Ionospheric Total Electron Content (TEC) is the total number of electrons in a column of unit cross section extending from the transmitter to the receiver. TEC is calculated... -
Measurement of Incoherent Scatter
For radio waves transmitted through the ionosphere with frequencies much larger (50 to 1300MHz) than the plasma frequency (up to 15MHz), very small-scale fluctuations of... -
Ovation Prime Real-Time
The Ovation Prime Real-Time (OPRT) product is a real-time forecast and nowcast model of auroral power and is an operational implementation of the work by Newell et al (2009).... -
Ionospheric Oblique Incidence Soundings by Satellites
The oblique incidence sweep-frequency ionospheric sounding technique uses the same principle of operation as the vertical incidence sounder. The primary difference is that the... -
Measurements of the Absorptive Properties of the Ionosphere
Absorption of radio waves occurs when electrons responding to the wave fields collide with and transfer energy to the neutral particles. A study of ionospheric absorption yields... -
Sudden Ionospheric Disturbances (SID)
Sudden ionospheric disturbances (SID) are caused by solar flare enhanced X-rays in the 1 to 10 angstrom range. Solar flares can produce large increases of ionization in the...
